test

I just got a catalog in the mail and saw this and though I should share it.:mrgreen::bigjoint::wall: HaHA If you have to test that nug then just give up! In no way is this trying to advertise botrytis tests, please learn how to identify bud rot using your own brain.o_O

Hey Yall. I started a winter project in my garage last month. RDWC with 400w HID lighting. Open Space Grow in a "insulated" garage. This is more of a test, considering the odds are stacked against me. Specs are down below. Ill post some pictures later. One thing I'm noticing off the bat is the...

The light spread is excellent and in our test the fixture output an average PAR of 698 µmols/m²/second over the 3ft x 3ft plant canopy an consumed 278.1 watts for a calculated system efficiency of 2.03 µmols/watt or usable PPF/watt. It is very solidly built light that has a quality feel and all...

I call this the “Hanukkah” cut. What do you guys think? Took a little bit long to root but once it did it’s been doing amazing, and she is branching out exactly the way I imagined she would in that “menorah” shape. Grape OG cut. Not really sure if it will provide any benifits but maybe I’ll run...

So I just harvested 5oz, dry weight. All clones, same strain, 5 plants in 1 gallon smart pots. Previous harvest was about 11oz, same strain, but 2 plants this time grown in 5 gallon pots. I only did the 1 gallon pot grow to prove to my father in law that pot size matters when it comes to yield...

How many ml of my water do I put to 2 drops of the solution I don’t have the tube with this kit just want to get a good reading thanks for the help

Hey guys has anyone used the thc and cbd test kits to measure there buds for cbd percentage? Here’s their website https://test4kits.com.au/en/. Keen to get feedback if they are accurate. Cheers

Anyone have any thoughts about the best way to get product lab tested while living in a cannabis-unfriendly area of the US? I can live without it normally but I'm growing some high CBD plants and it's important to me to know as much as possible about the THC: CBD ratio to find the gal most worth...

Hi everyone, my first thread on here and I want to say thank you to the people who have been patient as a few have been waiting. I am going to upload a few pictures of the test equipment I am using to do these tests and follow up a big later as I want to go and have a beer on my Sunday afternoon.

Hey everyone, after reading about the membrane meniscus hydroponic system on Larry3215's thread: https://www.rollitup.org/t/three-types-of-hydro-in-a-small-tent-on-one-airpump.960095/ I did a little digging, got in touch with the inventor Andrew Parker and also read his book on the system. On...

My partner attended a pre-employment drug test today and had an invalid result for THC. He was tested with Proscreen Cup here in New Zealand. Every other reading was negative, however THC came back as an invalid reading (neither positive or negative). They re-tested and it came back invalid the...

I had added a few co2 bags to a few of my previous grows. I had two given to me by a friend. I haven't really had consistent genetics till now. The same buddy sent me a co2 kit that he didn't need and I would like to see if it will really help my specific setup. I know it is relative to few...

Rollitup, I want your input! I'll end up growing the winning entry, or in the event of problems the runner up. I've been selected as one of the testers for the Geyapex COB lights, specifically the LM-P4 model. This will be going into a Des Jardin 2x2x5 tent, making for 55w of COB per sq/ft...

I moved one of my NLA into a new grow area with 9 150w, actual 45w 405w with 24,300 lumens @ 2700k. The other is under 12 100w, actual 23w 276w 19,200 lumens @ 6500k All clf bulbs Lights are running for 18/6 Both are 23 days old So the experiment begins to see what works better

I apologize if this is the wrong area to post this. I thought I'd share this because there isn't a whole lot of information on it. I read that weight loss while detoxing causes it to stay in your system longer. I have been clean 6 weeks now and still pissing positive based on tests I bought...

No I'm not talking about a TDS/EC reader. I'm more interested in what you guys are using, if any, for individual chemical tests, within your nutrients (e.g. Colourimeters, ect.)

Hello, I am unsure whether this is a positive or negative test for THC (picture attached). The line is not as dark as the test for the other drugs. What do you guys think? Thank you in advance.

Recently I let a friend store weed in my half full Tylenol bottle for about a day. Is there any chance of THC or any other indentifiers being transferred to the Tylenol from the buds? If so how much and so on? I had a drug test earlier this week and I completely forgot that I've been taking that...

Welcome fellow growers to my eBay led grow light test. I'm here for a 60 day experiment on a inexpensive 800w led cob grow light. Supposedly this light is full spectrum so we will see. Looks almost blood red, I will be pulling my 1000w out in a few days to make sure the test isn't compromised...
